“Am I actually making money on TikTok Shop?” It is the question every seller asks eventually — usually after a big sales month that somehow did not translate into cash in the bank.
The problem is not your sales volume. The problem is that TikTok Shop has more than 10 different fee types that sit between your gross revenue and your actual profit. If you are calculating margin with just selling price - product cost, you are overstating your profit by 15–30%.
This guide walks through the exact formula, step by step. At the end, you can plug your own numbers into our free profit calculator.
The Master Formula
Here is the complete profit formula used by professional TikTok Shop sellers:
The AxonRow 5-bucket profit formula — the same calculation running on every order in real time.
And the margin percentage:
Profit Margin (%) = Kept ÷ Earned × 100Let’s break down each component.
Step 1: Start With Earned (Not Selling Price)
The Earned bucket starts with what the customer actually paid, including any shipping fees and taxes collected at checkout, plus any platform subsidies credited to your account. This is the number TikTok reports in the Order API as total_amount plus subsidy adjustments.
Common mistake: Using your listed selling price instead of the actual total. If you offer a seller discount or the customer uses a platform coupon, the total amount will be lower than your listing price. Always start from what was actually collected.
Step 2: Subtract Taken — Tax Component
In VAT-inclusive markets like the UK, tax is embedded in the total amount and flows through the Taken bucket as a pre-payout deduction — it was never your money to keep.
| Component | Description | Example (UK) |
|---|---|---|
| Product Tax | VAT / sales tax on the product | £4.17 (on £25 item) |
| Shipping Fee Tax | Tax on the shipping charge | £0.67 (on £3.99 shipping) |
| Taken — Tax Total | Sum of all tax components | £4.84 |
In the US, sales tax varies by state and is often added on top of the listed price. Either way, it must be subtracted from your revenue — it was never your money.
Step 3: Subtract Taken — Platform Fees
This is TikTok’s cut. The platform commission (referral fee) is the biggest component, but there are several smaller fees that add up — all sitting in the Taken bucket:
| Fee | How It’s Calculated | Range |
|---|---|---|
| Platform Commission | Total Amount × Category Fee Rate | 2% – 8% |
| Handling Fee | Logistics handling surcharge | Market-dependent |
| Small Order Fee | Flat fee on low-value orders | £0.30 – £0.50 |
| Retail Delivery Fee | State-level delivery tax (US only) | ~$0.29 |
Pro tip: The commission rate varies by product category. Beauty and personal care can be as low as 2%, while electronics may be 8%. Check your TikTok Seller Center for your category’s exact rate.
Step 4: Subtract Taken — Affiliate Commission
If you use TikTok Shop affiliates or creators to promote your products, their commission also sits in the Taken bucket and is calculated per line item:
Affiliate Fee = Sale Price × Quantity × Affiliate Fee Percent (per line item)Affiliate rates typically range from 10% to 30%. This is separate from the platform commission — you pay both. A product with 5% platform commission and 20% affiliate rate means 25% of your revenue goes to fees before tax and COGS.
If you don’t use affiliates, this pool is zero. But if you do, it is often the single largest deduction on your order.
Step 5: Subtract Spent — COGS
Cost of Goods Sold sits in the Spent bucket — a post-payout expense you control. It is calculated per line item in the order:
COGS = Σ (Unit Cost × Quantity) for each line itemThis is the one variable you fully control. Negotiating better supplier prices or optimizing packaging directly improves your margin.
Important: Use the cost at the time of order, not your current cost. Supplier prices change — if you bought inventory at £7/unit last month and it is £6.50 now, the order placed last month should use £7.
Worked Example: £30 Order With Affiliate
Let’s calculate the profit on a UK order: £30 total amount, 5% category commission, 15% affiliate rate, £8 product cost, 1 unit.
Without the full formula, a seller might calculate: £30 − £8 COGS = £22 profit (73% margin). The real number is £11 (36.7%). That is a 47% overestimate.
Same Product, No Affiliate: The Difference
What if the same order came through organic traffic instead of an affiliate?
The affiliate drives volume, but each sale earns you £4.50 less. Whether that trade-off is worth it depends on your organic reach. This is why tracking profit per order matters — averages hide the real picture.
When Margin Goes Negative
It happens more often than sellers think. Here is a scenario:
- £9.99 product (low-price accessory)
- 20% VAT (Taken): −£1.67
- 8% commission (electronics, Taken): −£0.80
- Small order fee (Taken): −£0.50
- 25% affiliate (Taken): −£2.50
- COGS (Spent): −£4.00
- Kept: £0.52 (5.2% margin)
One return or one additional discount and you are in the red. Low-price items with high affiliate rates are the most dangerous combination on TikTok Shop.

Key Takeaways
Selling Price − COGSis not profit. It ignores tax, platform fees, and affiliate cuts.- The full formula: Kept = Earned − Taken − Spent − Lost. Taken covers all pre-payout deductions; Spent covers COGS and ad spend.
- Affiliate commission (10–30%) is often the largest single deduction — track it separately in the Taken bucket.
- Low-price items with high affiliate rates can easily go negative after all fees.
- Calculate margin per order and per SKU, not as a store-wide average.
